Construction of the Bicyclooctane Ring System by an Intramolecular Diels-Alder Reaction - A Synthetic Approach to Atisane

1,2,3,4-Tetrahydro-6,7-dimethoxy-1-(3-methoxybenzyl)-2-methylisoquinoline (3) was converted into the olefinic enone (7).After formation of the corresponding silyl enol ether (8), intramolecular Diels-Alder reaction of the triene (8) produced two stereoisomers of 3,10-ethano-3,4,4a,9,10,10a-hexahydro-6,7-dimethoxyphenanthren-2(1H)-one (9), one of which was transformed into the exomethylene (13) and the olefinic methyl compound (16).

SYNTHETIC APPROACH TO DITERPENE ALKALOIDS - A SIMPLE AND NOVEL SYNTHESIS OF THE A, B, C AND D RING PART FROM 1-BENZYL-1,2,3,4-TETRAHYDROISOQUINOLINE

The synthesis of the A, B, C and D ring part (13) of diterpene alkaloid atisine (5) from 1-benzyl-1,2,3,4-tetrahydroisoquinoline (6) by use of an intramolecular Diels-Alder reaction is described.
